Abstract: In this paper, a case study on reduction of high-frequency disc brake squeal by modification of pad shapes is presented. The aim is to give an intensive analysis on the phenomena of pad shape effects on disc high-frequency occurrence. For the analysis, a complete closed-loop coupled modal synthesis model is built. A series of analyses is performed, such as complex eigenvalue analysis, substructure modal composition analysis, substructure modal parameter sensitivity analysis, feed-in energy analysis, etc. The simulation analysis gives reasonable explanations of pad shape effects on high-frequency brake squeal occurrence.
